Illinois River - Cave Junction, OR

The Illinois River, flowing through rugged terrain near Cave Junction, Oregon, is a designated Wild and Scenic River and a critical stronghold for wild salmon and steelhead. This challenging yet incredibly rewarding river sustains robust populations of wild fall Chinook and Coho salmon, and wild winter steelhead, alongside resident and sea-run cutthroat trout. Its remote character and pristine beauty are as significant as its powerful fish.

Angling success on the Illinois is largely dictated by natural flow regimes. The river typically becomes fishable in late spring and summer after high winter and spring runoff, providing optimal conditions for resident trout. Fall and winter bring the migratory salmon and steelhead runs, though high-water events can make fishing difficult. Fly fishing is a highly effective and popular method here, with anglers employing nymphs, streamers, and dry flies for trout and steelhead.

Access can be challenging due to the river's rugged nature, often requiring hiking or rafting for reach. Anglers must always respect private property boundaries and prepare for wilderness conditions. Conservation is paramount on the Illinois River; strict adherence to Oregon Department of Fish & Wildlife (ODFW) regulations, including specific gear restrictions and often mandatory catch-and-release for wild anadromous species, is crucial. The Illinois River provides an unparalleled wilderness angling experience for those committed to wild fish conservation and a challenging adventure in a truly unspoiled environment.
